Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides a method for installing flexible fluid pipes for passing fluids such as hot water, water, gas, etc. behind a wall, and then connecting a joint to the end of the fluid pipe. This relates to a piping structure in which the end of the fluid pipe can be pulled out from within the sheath pipe to the wall surface for inspection, repair, or replacement of attached or attached fittings, faucets, gas tanks, etc. be.

(Prior Art) Conventionally, as shown in FIG. 5, a flexible fluid is stored in a sheath pipe 110 that is pre-piped behind a wall from a fluid supply section 100 for hot water, water, gas, etc. to a fluid consumption section such as a joint storage box 200. A piping structure has been proposed in which the pipe 130 is inserted therethrough. and,
In this conventional piping structure, the fluid pipe 13
0, or when inspecting, repairing, or replacing the attached fitting 150, water faucet, gas tank, etc., the fluid pipe 130 is removed from the inside of the sheath pipe 110.
Fluid supply unit 100 to draw out the end of the
It was necessary to cut off one end of the fluid pipe 130 that was fixed to the. Therefore, the applicant has already filed a patent application in 1983.
- In Japanese Patent No. 165940, a fluid tube protector 400 approximately shaped like a stomach bag having a slack storage portion shown in FIG. 6 was proposed,
Even though the fluid pipe 130 is guided by the sheath pipe 110 of a certain length, the extra length is placed behind the wall, and the fluid pipe 130 can be inserted from inside the sheath pipe 110 without cutting off one end of the fluid pipe 130. The end of the wall is being pulled out onto the wall surface.

(Problems to be Solved by the Invention) However, the above-mentioned fluid protector has problems in that it is expensive to manufacture and difficult to use frequently.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a piping structure for a fluid pipe that is extremely simple and inexpensive and allows the end of the fluid pipe to be pulled out from inside the sheath pipe to the wall surface without cutting off one end of the fluid pipe. Our goal is to provide the following.

(Means for Solving the Problem) In order to achieve the above object, in the piping structure of the present invention in which the fluid pipe can be freely taken out and put back, the fluid pipe joint is housed and installed in the wall, and the joint is placed on the wall surface. A joint storage device includes a facing storage portion and a cylindrical portion that communicates with the storage portion; a sheath tube connected to the cylindrical portion; a sheath tube inserted through the sheath tube and the cylindrical portion of the joint storage device;
a flexible fluid pipe whose end is connected to the joint, and the other end of the sheath pipe is slidable relative to the cylindrical part of the joint housing so that it can reciprocate in the connection direction. When the fluid pipe is taken out and put back in, the other end of the sheath pipe is slid, and the joint to which the fluid pipe is connected can be taken out and put back out of the storage device.

(Function) According to the above configuration, since the fluid pipe is inserted into the sheath pipe, piping can be easily installed even in a narrow space behind a wall. Further, the joint to which the fluid pipe is connected is stored in a storage part of a joint storage device installed in the wall and faces the wall surface. When inspecting, repairing, or replacing a fitting, faucet, gas tank, etc., by pulling out the fluid pipe, the end of the sheath pipe is reciprocated in the cylindrical part of the fitting storage device, and the fitting is removed together with the fluid pipe. The joint can be stored in the joint storage device by pulling it out from the storage device toward the wall surface and pushing back the fluid pipe.

(Example) Next, an example in which the present invention is embodied in a fluid pipe for hot water will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the proximal end of the sheath tube 10 is fixed to the sheath tube holding section 101 of the fluid supply section 100 for hot water, water, etc. behind the wall. Fitting storage box 2 as a fitting storage device which is a fluid consumption part
00 is box-shaped and consists of a storage section 202 whose front side opens to the wall surface, and a cylindrical section 201 that communicates with this storage section 202 and protrudes from its lower part.
It is fixed to the lower surface of the crosspiece 1 with screws and installed in the wall. The tip end, which is the other end of the sheath tube 10, is slidably connected to the cylindrical portion 201 so as to be able to reciprocate in the connection direction, that is, in the direction of the arrow shown in FIG.

A flexible fluid pipe 30 for passing fluids such as hot water and water is installed inside the sheath pipe 10 and the housing part 202, and a fluid pipe joint 50 is connected to the tip of the fluid pipe 30. This fluid pipe joint 50 is housed in the housing section 202.

Now, in order to pipe the fluid pipe 30 using the sheath pipe 10, the joint storage box 200, etc. described above, as shown in FIG.
The proximal end of the sheath tube 10 is fixed to the sheath tube holding part 101 of
The tip of the sheath pipe 10 is connected to a joint storage box 200.
It is slidably engaged and connected to the cylindrical portion 201 of.
Note that if a water stop material such as an O-ring is placed at the connection between the cylindrical portion 201 and the tip of the sheath tube 10, the sheath tube 10
Fluid can be prevented from leaking from inside.

After erecting a wall following the piping of this sheath pipe 10, a flexible fluid pipe 30 is inserted and piped into the sheath pipe 10, and a fluid pipe joint 50 is connected to the tip of the fluid pipe 30. By doing so, the piping work for the fluid pipe 30 can be easily completed.

Attaching the fluid pipe fitting 50 to the fluid pipe 30 or inspecting the attached fluid pipe fitting 50;
For repair or replacement, the tip of the fluid tube 30 is pulled out from the wall surface as shown by the two-dot chain line in FIG. Then, the tip of the sheath pipe 10 is moved from the state shown in FIG. 1 to the joint storage box 2 as shown in FIG.
00 slides in the connection direction, that is, toward the main body side of the joint storage box 200, and the fluid pipe 3
0 and the fluid pipe fitting 50 are pulled out from the storage section 202, allowing work to be easily performed in a wide area on the wall surface. In addition, after the work is completed, the fluid pipe 30
By pushing the fluid pipe 30 back into the sheath pipe 10, the end of the fluid pipe 30 and the fluid pipe fitting 50 can be stored in the storage part 202.

Therefore, piping work, maintenance, and inspection can be performed without cutting off one end of the fluid pipe 30 with a very simple and inexpensive configuration using the joint storage box 200.

In addition, FIG. 4 shows another embodiment in which a joint storage tool 300 is used in place of the joint storage box 200. , and an inverted L-shaped mounting piece 303, and a storage portion 304 is formed on the side of the mounting piece 303. Then, the fluid pipe joint 50 stored in this storage section 304 is directly connected to the crosspiece 1.
It is fixed to the bottom of the.

Furthermore, the present invention is not limited to the above embodiments, and may be implemented as a fluid pipe for connecting a gas tank or the like, or as a feed pipe from a fluid consuming part to another fluid consuming part. In this case, modifications may be made as appropriate without departing from the spirit of the invention, such as embodying the invention or implementing the joint storage tool main body and the cylindrical part separately and assembling them together. It may also be carried out.

(Effects of the Invention) As described in detail above, in the present invention, the fluid pipe is inserted into the sheath pipe, so the structure is inexpensive and piping can be performed very easily even in a narrow space behind a wall. In addition, the fluid pipe joint is housed in the housing part of the joint storage device installed in the wall, and the tip of the sheath pipe is slidably connected to the cylindrical part so that it can reciprocate in the connection direction, so that The fluid pipe joint is housed in the wall, and when repairing, the fluid pipe joint can be pulled out from the housing part of the joint storage tool to the wall surface without cutting off one end of the fluid pipe, which is an excellent effect.
